DRY criosnr.

To all whom t may concern.' y

Be it knownthat I, FRANK FAvmir, Jr., a citizen of theUnited States, residing at Westminster, in the county of Adams and State of Colorado, have invented certain new and useful Improvements in Dry Closets; and l do hereby declare the followingV to be a full, clear, and exact description of the invention, such `as `will enable others skilled in the artto which at appertains to A.

make and use the same. A

`This invention relates to improvements in dry closets of a ventilated sanitary 'indoor designed for usefon the farm, homestead, or

other outlying localities, where the facility of city sewerage is not available, and hence the usual water liushing closets are not feasible for installation` Their object, therefore, is to provide a dry closet for use indoors, which is effectively odorless and substantially sanitary, rendering the same largely unobjectionable in these highlyV essential requirements.

rlhese ends are broadly accomplished by the employment of a portable container, charged with a liquid mixtureimpregnated with a suitable chemical of a non-combustible and substantially non-poisonous nature, vbut which has sufficient strength to function as a germicidal deconiposer and vdeodorizer, to throw down or destroy the acids, stench and poisonous gases arising from the fecal and urine contents.

While certain advantages of this `type of closet are manifest, still many of them, as

heretofore constructed, have proven more or less objectionable and unsatisfactory in practical use, and my main object is to improve conditions generally, providing at the of which v y Figure l, is a vertical sectional view,

4same time, and at lowcost of manufacture, a durable and effective` portable closet, adapted to be coupled upwith a vent pipe, through an` improved form of detachable connection, the whole Vequipment being designed for ready installation, by the purchasers themselves, with comparatively little trouble and expense-an end especially desirable `in sparsely settled localities.

Having thus generally stated the object of the invention, ll will now describe more fully the improved construction and combined arrangement of parts, the special features of novelty being more succinctly set forthin the appended claims; and in order to clearly understand same, reference is had to the accompanying. drawings, forming a part of this application, in which drawings like parts `are designated by the same referi encenuinerals throughout the several views,

taken on a planethroughthe closet proper and its coupled connections `with its vent Fig. n details of the coupled connections;

Fig. 3, is an enlarged sectional view, illustrating thefacile means of making an air tight joinder between the upper shell and lower container, where a two part receptacle is employed, as shown in Fig. l;

Fig.y t, is a detail sectional view on` the line d-t of Fig.` 2; and i 2, is a similar enlarged view of the Fig. 5, is an elevational view partly i broken away, of a slightly modified arrange- `ment, employing a unitary form` of container, instead of the two-part construction of Fig. l.

l designates a vent pipe leading to the atmosphere in anyv suitable manner, but it may preferably terminate above the ridge pole of the building.

To the lower end of this ventpipe l `is telescoped the hollow end 3 of a support 2, y

providing an upper vent chamber, fixedly secured in place, as to the wall or floorof a room. In practice this may simply be ai tubular standard or pipe, having a iianged base 3, screwed or bolted to the Hoor, as shown. Y

The upper vent chamber of this tubular standard 2 has a lateral upturned elbow 4 associated, through interposed means, withV a specially formed' hollow element of the container receptacle, hereinafter described,

to provide a readily lattachable anddetachable air tight connection therebetween.

Broadly,'this air-tight readily attachable and detachable coupling might be made through more -or less rigid connections, em-

ploying certain features of my 'improvements. However, l have shown Vand will now ,describe in detail a connection provided with an equalizingor self adjusting element `for insuring an air tight joinder; l

To this end, the rip-turned portion of the elbow 4 maybe threaded to receive a threaded'membier 5, functioning asa guiding sleeve or' receiving part forl the lower end of'a hollow open-'ended retractile element 6', be-

I tween the bottom edge 4of which and theupper ,edge ofthe elbow L1- is interposed a spring`7, preferably of coiled formation.v

The' lo'wgend of the element '6 maybe Y 10, for establishing an air sealing contact with the h'ollowfprojecting element ofthe container receptacle, before referred to and 'which will presently be described.

In the illustration, the upperv end of the element 6 is simply shown as having an eX- ternal flange, bent inwardly upon itself and thence slightly upwardly, to provide a recessed seat 11 for the vgasket 1'0, which latter may be of rubber, leather, or other suitable form vof cushioning elastic material.

The removably@connected portable container itself is indicated at 12 in Figs; 1 and 3, 'and atl?) 'in Fig". 5; lt-may be provided with the usual bail or handle 14.

vWhether the closet be built up sectionally or of unitary formation for its full height, in both Vcases the upper portion' of the peripheral wall is apertured and provided,

with a communicating hollow lateral eXtension or projection 15, which may be of substantial voval contour as shown, if desired, the outer end being closed as at 16, and its underneath wall depressed inwardly to form a beveled-faced seating recess v17, the de pressed underneath wall being suitably apertured, indicated by a single large orifice or opening'lS, which is adapted to register into the apex of the recess.

with thc tubular retra-ctile element 6, when the fixtures are assembled in connected relation as referred to later.

In the two-part receptacle, illustrated in Figs. 1 and 3, the top Section is in the form of a surmounting shell 19, the upper end of which is bent inwardly as a downwardly inclined marginal rim 20, providing the central enlarged opening 21.

The lower end of the shell is curved inwardly an-d downwardly, as at 22, and is also open as indicated at 23.

On the outside of the lower portion of the, upper shell19 is suitably secured a skirted or outwardly iiaring encircling member 2l, which with the inwardly curving lower poi tion of the shell provides an annular diverging or crotched seating recess, obviously adapted to readily adjust itself on top of thel lower Ycontainer proper, an air tight joinder or seal being made by the insertion of a Suitable cushioning gasket 25 inserted well up This arrange ment'wi-ll alsoprevent the soil and urine from being splashed up and slopping over the container-a very objectionable feature in point of cleanliness and sanitation.

26 'designates the usual apertured toilet seat, having the lid 27 hinged thereto at 2S, and the seat, int-urn, hinged at 29 to the hollow `extension 15, the arrangement providing for the use of the closet both as a covered stool and urinal.

These analogous parts are designated by similar numerals in Fig. 5, but in this latter figure, the marginal rim 20 is omitted, the top of the container 13 being formed like the lower container 12 of Fig. 1, to permit of the contents beingv easily dumped and the container thoroughly cleaned and iiushed out, when removed for emptying.

'As in the non-ventilated form of chemical closets,` I also employ a suitable chemical mixed in liquid form, but with the additional ventilating features, of course, the noxious odors and gases, not entirely killed by chemical action, are'conductcd away, as indicated by the arrows, through the connections t'o the vent pipe 1,- and from thence are discharged exteriorly of the building.

Then the closet is dissociated from its vent connections, the tubular clement 6 will be forced upwardly under pressure of the spring 7, but it cannot be entirely displaced and lost, owing to the limiting stop elements 8 and 9.

But when the container receptacle is in position andthe upper shell section of Fig. 1 is being replaced thereon, the crotched recess at its lower end will readily guide itself into air-tight connection with the top of the container below, especially made air-tight through the interposition of the gasket V25. At the same time the bevel-faced recess or Laisser depression 17 will find and guide itself into sealed relation with the upper open end of the tubular retractile element 6, throughits seated gasket 10, which retractile element will be accordingly forced downwardly; but the spring tensional force upwardly thereon willequalizingly balance or cause the retractile element to adjustably accommodate itself to the opposing forces, and with the gasket 10 will always insure an intimate non-leak connection, although at the same time providing a readily separable joinder or coupling between the coperating parts.

lhe only differences between the slightly modified disclosure in Fig. 5 and that of Fig. l are in the construction of the container itself as a unitary receptacle, and therefore require no further specific description as to operation.

The connections as set forth have been found to ordinarily suffice for venting purposes, but if desired, it will be obvious that any of the well known means of forced draft sometimes used in ventilation systems, such as a -current of generated heated air or the suctional or propulsive force created by a fan or blower, may be employed.

While l have thus fully described a practical and preferred embodiment of the in vention, still it will be understood that l do not limit myself to the exact details as set forth, excepting as come within the purview of the ensuing claims and a reasonable construction of the scope thereof contemplating a 'fair range of equivalents.
